I wanted the map occupied the entire width of the header or section.
The section is almost 100%, but with margins. In the header it seems as if the fluid container function does not work with the map.
It is rare why it works with any image.
The plugin lets you adjust the map width to 100%.
I decided to put the map in a section contained for now. If the customer wants the width to 100% will try other plugins.
thanks!
